Use formulas to find the lateral area and surface area of the given prism. round your answer to the nearest whole number.

a) 755 m^2; 815 m^2
b) 755 m^2; 785 m^2
c) 725 m^2; 815 m^2
d) 725 m^2; 785 m^2

B. ; .

Step-by-step explanation:

We have been given a triangular prism and we are asked to find the lateral surface are of the prism.

We know that lateral surface area of prism equals to the product of perimeter of base of prism and height of prism.

, where,

p = Perimeter of base,

h = Height of the prism.

We will find the perimeter of triangular base of the given prism as:

Therefore, the lateral surface area of our given prism is .

The surface area of the given prism will be equal to the sum of area of each face of the prism.

Therefore, option B is the correct choice.

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
